| Abstract: | A method of constructing general solution of general nonhomogenous linear differential equation of the n-th order with constant coefficients is presented and, the method of constructing general solution of nonhomogrnous linear differential of only the second order with constant coefficients is extenided. By using our method, the general solution needed of the questions of reality is got. |
